Windshield install - gasket to body first?

I've read several windshield install threads and can't decide whether to put the gasket on the body first, then work in the glass (or put the gasket on the windshield and work the assembly onto the body).

The FSM for my '72 Dart says to apply the gasket (with butyl sealer) to the body first.
But many other threads say it's easier to put the gasket on the glass and use a rope to pull the lip of the assembly over the body fence.

What's the best way for a novice (me) to do it, with the lowest chance of breaking the glass or tearing the gasket?

thanks

We always put the gasket on the glass . and then use the rope to work it in the car
